This paper presents the first results of a study aimed to assess the use of multidate ERS-1 SAR data for temperate forest applications over hilly terrain. The study was conducted over a mountainous French forest test-site. We first present a new radiometric correction method using SAR image simulation and a DEM to calibrate the data corrupted by ground area variability within pixels (up to 10 dB) and correct the data for s° angular response (up to 1.5 dB). Both corrections are included in a SAR post-processing chain necessary to obtain optimized geocoded multitemporal s° images.Preliminary results showed that uncorrected data over hilly terrain are useless for discrimination purposes. After the validation of the radiometric correction, corr...
